APPARATUS Fon HYDRATING, PULPING, 'on REDUCING MATERIAL 1N A WET onsEMInIQUID STATE.

Application filled May 14,

To all whom 'it may concern Be it known that I, HAROLD JACKSON, aBritish subject, residing at Garstang, county of Lancaster, England,have invented certain new and useful Improvements in Apparatus forHydrating, Pulping, or Reducing Material in a Wet or.Semiliquid State,of which the following is a speciication.

This invention relates to improvements in apparatus for hydrating,pulping or reducing material in a vet or semiliquid state Isuch asdescribed in the specifications of my former applications for patentsSerial Nos. 614,165 and 614,166, led March 1e, 1911, in which a gentlehammering or tapping action is obtained by the centrifugal action ofbeaters against a corrugated or serrated surface. I find that thisaction can be obtained by a revolving disk carrying beaters operatingagainst a corrugated casing or by beaters pivoted to the casingoperating against a corrugated disk or by a combination arrangement ofsuch beaters.

The' invention will be fully described with reference to theaccompanying drawings, in whichv Figure l is a side elevation partly insec# tion. Fig. 2 is a sectional plan on line :z2- 40,

looking downward. F ig.' 3 is -a sectional" I ing A through which thematerial to be pulped Hows, and a'horizontal disk B mounted therein on ashaft C to which a rotary motion is given. The upper surface b of thedisk is formed with a series of shallow ribs or projections set eitherradially or tan-` gential to a circle at some distance from the center,and the horizontal portion a of the casing below the disk and also thevertical portion a beyond the periphery of the disk are similarlyribbed.

To the horizontal portion a2 of the casing A above the disk B a numberof beaters D arepivoted so that their faces rest .upon the ribbed uppersurface of the disk. The beaters D may be made with two faces, one (l torest upon and strike the projections on the disk and the other to strikethe casingv should they rebound.

of the disk similar beaters D are pivoted which restupon the ribbedhorizontal portion a of the casing. Similar beaters D are pivoted to theperiphery1 of the disk B lto come into contact with the vertical ribbedportion a of the casing. These peripheral beaters may be placed to actasv screw propellersy to force the material 'through the casing. All thebeaters may be pivoted to the casing, the diskbeing ribbed on both sidesand the lower set of beaters held vagainst it by springs, or all thebeaters ma)Y be pivoted to ythe disk, those on the upper surface beingheld up against the casing by springs.

If desired, the machine may be placed horizontally with a horizontalshaft and vel'- tical rotary disk. In such case the beaters will bepivoted to both sides of the rotary disk and the casing will beribbed atboth sides. Or the beaters may be pivoted t0 the casing at both sides ofthe disk andv forced against it by-springs, the rotary disk `beingribbed on both sides.

VAs the disk rotates, the beaters pivoted to the casing are caused topatter thereon'and are .thrown to and fr0, giving a gentle hamvTrieringor tapping action to the particles of fiber or material liowing through.Similarly the beaters pivoted to the underside and to the periphery ofthe disk are carried around with the disk, over the lower surface andagainst the vertical sides'of the casing, and a similar movement isimpa'rted to them.

When the upper and lower sets of beaters are both pivoted to the casing,the upper set rests as above described on the upper corrugated surfaceof the disk and the lower set is held up by springs or other suitablemeans against the under corrugated surface of the disk.

Where the upper and lower set of beaters are `both carried by the disk,the upper set is held up against the upper part of the casing by springsor the like, and the lower set is pivoted to the under side of the diskand rest upon the lower corrugated surface ofthe casing.

The pivots of the beatersmay be set tangentially to a circle concentricwith the periphery of the disk or radially or they may be otherwisearranged, and the Weight of the beaters may be varied as they are placednearer to the periphery of the disk.

Two sets of rotatingl disks may be arranged, with the beaters of onestriking against the ribs of thel other, or two or more sets of diskswith their casings may be superimposed, the material flowing from one tothe other.

- `The action ofthe rotary beaters against the stationary ribs or of thestationary beaters against the rotating ribs is a gentle hammering ortapping action on the materialy and ribs on the surface of the casing,substantially as described.

2. In apparatus forhydrating, pulping or reducing material in a wet orsemi-liquid state, the combination with a casing, of beaters pivotallyconnected thereto, a rotaryl disk having a ribbed surface against whichthe beaters contact, beaters pivotally connected to the disk both on theperiphery and on the under surface, and ribs on the casing against whichthe secondnamed beaters contact with a gentle hammering action,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
